As previously reported, Black Sabbath will appear on the show, performing a new song, “End Of The Beginning.” The season finale episode, titled “Dante’s Inferno,” will feature band members — Osbourne, guitarist Tony Iommi and bassist Geezer Butler — sharing a scene with D.B. Russell, Ted Danson’s character.

Ozzy also shares a scene with John Merchiston, played by James Callis (who Battlestar Galactica fans may remember as Dr. Gaius Baltar from the well-loved SyFy series). Watch the scene here.

Meanwhile, 13 drops on June 11, and their U.S. tour kicks off July 25 in Houston. CSI: Crime Scene Investigation airs tonight on CBS at 10 p.m. ET/PT.
